KILN.

Specification of Letters Patent.

Patented Feb. 3, 1920.

Application filed September 8, 1919. Serial No. 322,566.

To all whom it may concern:

Be it known that 1, JOHN ELCOCK, a citizen of the United States, residing at C0- lumbus, in the county of Muscogee and State of Georgia, have invented a new and useful Kiln, of which the following is a specification.

This invention relates to down draft brick kilns and is designed more especially as an improvement upon the kilns disclosed in Patents 7 67 ,637 of Aug. 16, 1904 and 824,919 of July 3, 1906.

One of the objects of the invention is to provide fire boxes which are so located that after the fuel has been coked therein it can be pushed back into the flash walls and burned.

Another object is to provide a novel arrangement of bottom and smoke flueswhereby the hot air is evenly distributed through the kiln.

Another object is to provide small air vents in the chimneys for cooling them at their points of connection with the dome.

WVith the foregoing and other objects in View which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims, it being understood that various changes may be made in the construction and arrangement of the parts without departing from the spirit or sacrificing any of the advantages of the invention as set forth in the appended claims.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings- Figure 1 is a horizontal section through the kiln.

Fig. 2 is a section on line 2-2, Fig. 1.

Referring to the figures by characters of reference 1 designates the floor and 2 designates the wall of a kiln of the ordinary circular type, the same being provided with the dome like top 3 having a vent opening 4. Constructed within and above the wall 2 at regular intervals are preferably four chimneys 5, each of which is provided close to the dome 3, with an air vent 6.

Parallel outlet slots'7 are formed in the floor 1 and extend thereacross at opposite sides of the center, the two slots or channels being connected by small flues 8 within the floor and by a central large flue 9, having an intermediate slot 10. Extending from each of the channels 7 are two smoke flues 11 for conducting smoke and hot gases to the respective chimneys. The smoke fines are so connected to the channels or depressions 7 that gases circulating within the kiln and flowing to the outlets will be distributed evenly throughout the interior of the kiln in flowing to the smoke fines.

Erected on the inner sides of the wall at regular intervals are flash walls 12 the bottoms of which are located back of the grates in the fire boxes 13 erected at the outside of the wall 2 and which are provided with ash pits 1a thereunder.

Coal is placed in the boxes 13 and allowed to coke. It is then thrust back into the flash walls and burned. The hot gases ascending from these flash walls will circulate downwardly and inwardly and escape down through the channels or slots 7 and thence to the chimneys by way of the flues 11, as before described.

What is claimed is 1. The combination with a circular kiln, of regularly spaced chimneys erected in the wall thereof, regularly spaced flash walls within. the kiln, fire boxes opening at their inner ends into the flash walls to deliver coked fuel thereto, parallel communicating channels in the floor of the kiln adjacent the center thereof, and smoke flues in the floor connecting the channels to the chimneys.

2. The combination with a circular kiln, of chimneys erected on the wall thereof and having air vents close to the dome of the kiln, flash walls in the kiln, means for supplying fuel thereto,communicating channels in the floor of the kiln adjacent the center thereof, and smoke flues in the floor and connecting the channels to the chimneys.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.

JOHN ELCOGK.
